This invention relates to a railroad construct on and has as its particular ob ect to provide a rail for railroads which is of heavier and more resistant construction than the rails as at present in use,

nation andarrangement of parts as will be hereinafter described, reference being had to the accompanying drawings in which Figure 1 1s a plan view of a rail forming a part of the railroad according to the inven- '6 tion.

modification.

' Referring 'more particularly to Figures 1 to 8, 1 indicates a rail having in section the shape of a reversed U of which the upper part the bolt.

has the profile of a head according to the usual railroad rails. V

The adjacent ends of two consecutive rails meet on the tie This tie supports the hori- Zontal branches 4 of a supporting member 5 which is also of reversed U shape in section and on which member rest the two ends of the rails. Clamping plates 6 are disposed on both sides of the two rail ends and are placed with the edges 7 on the flanges 3 of the rails, while the edges 8 of the plates abut against the raised edges 9 of the supporting member 5. V

13 represents a fastening device which conf nects the tie b, the supporting memberband" the clamping plate 6. This device comprises a bolt 10 (Fig. 7 provided with a head 11 and with two lateral grooves 14a adapted to engage the two branches of the U shaped key 14 (Fig. 8). A strong helicoidal spring 12 is engaged between the key 14 and the plate In order to assemble the fasteningdevice, the bolt 10 is inserted through corresponding holes in the three members to be clamped together and then the spring 12 is brought over This spring before being compressed reaches over the two grooves 14a.

By means of a tool which is not represented and which is-engaged in the grooves 13 of the bolt and comprises a lever arm adapted to act on the spring 12, this spring is compressed and then the key 14 is insertedin the grooves 14a, whereupon the tool is removed. The spring 12 then exertspressure between the plate (Sand the key 14 whereby the :rail 1 is firmly secured to the tie. A projecting cap 14?) may be placed over the key 14 and spring 12.

The tie b is provided with two apertures 17 engagingeach projection 16 of the supporting member 5 in order to prevent this member from any unintentional sliding movement-011 the tie. Thesupporting mem ber 5is also provided with two longitudi nally extending raised portions 18 against the inner edge of which the flange 3 of the rail abuts in order to prevent the two web portions 2 of the rail from spreading apart. v Between two ties b to which the ends of a rail are secured, the rail is fixed to alternate ties a by means of a similar device as above described and comprising the clamping plates 6, supporting member 5 and fastening device B. On alternate ties c the rail is supported by a tie plate 19 having two raised edges 20 and which plate is fixed to the tie 0 by means of a fastening device B as above described.

Itcould happen that one has to connect a track formed of ordinary T rails to a track composed of rails according to this invention. This case is illustrated on the right hand side of Figure 1 and in Figs. 4, 5 and G. The rail joint is supported by a sleeper of double width (Z. The end of a short section of T- rail 15 is deprived of its head C over a length 1 and penetrates into the interior of the rail .1 between the two branches of a supporting member 21 similar to the member 5 above described. Clamping plates 24 rest on the flanges 3 of the rail 1 and the foot D of the T-rail 15 and abut on the edges 9 of the supporting member 21. The clamping plates 24 and the member 21 are secured to the tie (Z by means of fastening devices B as above described. Fish plates 25 and 26 are disposed on both sides of the two railends to be joined and are suitably bent at 27 in order to coact with the webs 2 of the rail 1 and with the web 22 of the rail 15.

Inthe modification according to Figure 9 wooden ties e are used. The bolts 10 of the fastening devices B which secure the clamping plates 6, the supporting member 5 and the tie plate 31 to the tie e traverse the tie; a washer plate 30 is inserted between the heads 11 of the bolts and the tie. The tie plate 31 is also provided with apertures 17 engaging projections 16 of the supporting member 5.

In the modification according to Figures 10 and 11, the bolts 10 have their heads 11 engaged beneath the tie plate 32 which is secured to the tie e by means of wood-screws 35. In this construction first the tie plate 32 with the bolts 10 is placed on the tie and the screws 35 are screwed home with their heads turned into the position as shown in Figure 10. Then the supporting member 5 is placed over the bolts 10 and the rail 1 is placed ver the U-shaped portion of the member 5. Finally the clamping plates 6 are placed over the bolts 10 and the fastening device B is assembled. It is now not possible for the screws 85 to get loose since the supporting member 5 prevents the screw head from turning.

In the modification shown in Figure 12, the supporting member 37 is provided with longitudinally extending grooves 38 which are obtained by pressing the material so that corresponding projections 39 are termed on the lower face of the supporting member 37.

The grooves 38 are adapted to receive the edges 40 of the flanges 3 of the rail 1, while the projections 39 are engaged by grooves 41 provided in the tie 45. The clamping plates 6 and the supporting member 37 are again secured to the tie 45 by means of fastening devices B.

If a track formed of rails according to this invention is used for electric traction, the ends of two consecutive rails can be electrically united by means of a copper conductor 42 disposed between the head of the rail 1 and thesupporting member 37. The conductor 42 has its two ends 43 bent down wardly and inserted into vertical openings 44 provided in the supporting member 37.
